Wastewater operator continuing education

Nitrification: Alkalinity, Cold and Sludge Age

Training certificate — Rhode Island requires no renewal hours

Nitrification is fragile, and three things commonly knock it out: alkalinity runs out, the water gets cold, or the sludge age is too short. This hour covers watching each one and protecting the process when conditions turn.

Course summary, as it appears on your certificate

To equip wastewater treatment plant operators with a clear understanding of the critical factors affecting nitrification—alkalinity consumption, cold weather effects, and sludge age—and to provide practical guidance to maintain effective nitrification performance under varying conditions.

AquaCert does not mark its own homework: a licensed operator reviews the content and the course cannot be sold while that review is out of date.

One hour of study is one hour of credit. Your certificate reports the hours, which is what Rhode Island records against your renewal.
